ELECTRICAL IG-NITER.

Application filed April 25, 1921.

To all 'whom t may concera:

Be it known that I, JAMEs VVYLD, a subject of the King of Great Britain,residing at Queens Island, lBelfast, Ireland, have in- Vented new anduseful Improvements in Electrical Igniters, of which the following is aspecification.

This invention relates to electrical igniters and is especiallyapplicable for use in igniting oil furnace burners.

One object of my invention is to obviate the danger of the operatorbeing burned by the burst of flame which occurs when an oil burner isignited.

An igniter constructed according to my invention comprises carbonssupported by insulating material and preferably located in closeproximity to an oil burner, and means located at a distance from thecarbons and adapted to bring the said carbons together to strike an arc.

In one way of carrying out my invention the carbons are mountedcoaxially in housings of insulating material separated by spacingstrips. One of the carbons is fixed whilst the other carbon is connectedto a rod of conducting material which passes through an insulatin tubeand is provided with a knob or han le by means of which the carbon maybe moved against the action of a spring into contact with the fixedcarbon to strike the arc.

Current is supplied by a flexible twin cable to a connection box fromwhich the current is led to the fixed carbon and to the conducting rod.

In the accompanyin drawings which illustrate my invention *igure 1 is anelevation and Figure 2 is a detail longitudinal section.

l and 2 are carbons mounted coaxially in housings 3 and at and.separated by spacing strips 5, 5. The outer carbon l is fixcd to thehousing 8 whilst the inner carbon 2 is slidably mounted in a bushed tube6 of insulating` material fast with the housing 4. Secured to the carbon2 is a rod 7 of conducting material such as brass. Mounted on the end ofthe tube 6 is a connection box 8 to which current is supplied by afiexible twin. cable 9. One cable leads to a supply wire 10 connected tothe carbon 1 whilst the other cable is led to a terminal 11 to whichSerial No. 464,363.

one end of a spring 12 is attached, the other end of the spring 12 beingattached to a conducting screw 13 which serves also to secure to the rod7 an insulating handle lt by means of which the rod 7 and carbon 2 canbe moved against the action of the spring 12, so as to bring the carbon2 into contact with the carbon l to strike the arc.

The tube 6 and rod 7 are made of such a length as to obviate'the dangerof the operator being burned when an oil burner is ignited.

What. I claim is 1. In an electrical igniter the combination of a fixedcarbon, a movable carbon, means for supplying current to the carbons,housings for said carbons, an insulating tube connected to the housingfor said movable carbon, a rod of conducting material located withinsaid tube and connected to the movable carbon and means located at adistance from the carbons and adapted to bring the said carbons togetherto strike an arc.

2. In an electrical igniter the combination of a fixed carbon, a movablecarbon, means for supplying current to the carbons, housings for saidcarbons, an insulating tube connected to the housing for said movablecarbon, a rod of conducting material located within said tube andconnected to the movable carbon, a spring connected to said rod andadapted to cause the separation of said carbons and means located at adistance from the carbons and adapted to bring the said carbons togetheragainst the action of the spring to strike an arc.

8. In an electrical igniter the combination of a fixed carbon, a movablecarbon, means for supplying current to the carbons, housings for saidcarbons, an insulating tube connected at one end to the housing for saidmovable carbon and at the other end to a connection box, a rod ofconducting material located within said tube and connected to themovable carbon, and means located at a distance from the carbons andadapted to bring the said carbons together to strike an are.

4. In an electrical igniter the combination of a fixed carbon, a movablecarbon, means for supplying current to the carbons, housings for saidcarbons, an insulating tube connected at one end to the housing for saidmovable carbon and at the other end to a. connection bola a Yod ofconductng material located within said i'uhe and connected to then'ovable cm-'wn, a spring connected to said md and adapted to cause theseparaton of said (zal'bons and means located at a. distance from thecarbons an adapted to bring the said carbons together against the actionof flle spring to strike an are.

In testmony that 1 clafim the :Enregoing as 10 my inventon I havesgl'le'i my name this 19th day of March 1921:

JAMES WTYLD.
